PRESS.

SPECIFICATION forming part of Letters Patent No. 431,444, dated July 1, 1890.

Application filed January 8, 1890. Serial No. 336,295. (No model.)

. To all whom it may concern.-

Be it known that I, PARMER R. CROSS, a citizen of the United States, and a resident of Hammond, in the county of Lake and State? of Indiana, have invented certain new and useful Improvements inPresses; and I do herebyvdeclare that the following is a full,

clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in presses, and has especial reference toa press for pressing fruit, cheese, or other materials or matter. 0

The leading object of the invention is the The invention consists in the novel 0011- struction and combination and adaptation of parts for service, all as hereinafter described, and specifically pointed out in the claims.

Figure 1 represents a perspective view of the press. Fig. 2 represents a top plan view thereof, part of the frame being removed to disclose constructions. Fig. 3 represents a detail sectional view of one of the plungers and the operating mechanism therefor. Fig. 4 is a sectional view through part of the operating mechanism. Fig. 5 represents a detail view of the press-box. Figs. 6 and 7 represent detail views of the board on which the press-box rests.

Referring by numerals to the drawings, the numeral 1 designates the base or bed of the 'press, which is formed with a channel or gutter 2 for conducting the juice or liquid from the press-box. Rising from the base are posts or uprights 3, which are connected at the upper ends by the diagonally-arranged bars 4, and supported on the uprightsbetween the base and bars is a platform 5. Fixed in the center of the base, platform, and connectingbars is a rod or spindle 6, on which is fixed the sleeve 7, carrying the bevel gear-wheel 7, the sleeve 8, carrying similar bevel gearwheel 8 and the pinion 8 and the sleeve 9, fixed to the sleeve 7, carrying the pinion 9, all as clearly shown in Fig. 4. The large bevel gear-wheels 7 and 8 are what may be termed the operating gear-wheels, as they take their motion from the driving-gear. The gear 7 is securely fixed to sleeve 7, so as to revolve therewith, while the sleeve 8, carrying gear 8' and pinion 8 is loosely mounted thereon.

The numeral 10 designates the drive-shaft, mounted in bearings 11, and at one end of the shaft is the bevel gear-wheel 12 which meshes with the gear-wheels 7 and 8', and near the other end of the shaft is a ratchetwheel 13 and a gear-wheel 14, having a pawl 15 for engagement with the ratchet-wheel, whereby the gear-wheel will revolve the sh aft. The driving-shaft may be revolved by means of crank attachment to the end or by means of the shaft 16, carrying the pulley 16', and

the pinion 16 for engaging the gear-wheel14;

and having their upper ends 17 screw-threaded and formed each with a channel or groove 17 In this instance four of the plungers are employed, although I would have it understood that I may use a greater or less number, and four are shown merely as an illustration. The threaded ends 17 of the pistons engage the threaded thimbles 18, secured to the diagonal connecting-bars, and it will be seen that the rotation of the plungers in one direction will cause them to move upward and in the reverse direction will cause them to move downward, as is evident. On each of the plungers is loosely mounted a gear-wheel 19, which have the hubs 19 thereof formed with keys 19 adapted to enter the channels 17 of the plungers, and thus the rotation of the gear-wheels will be imparted to the plungers. The gear-wheels 19 are adapted to engage with either of the pinions 8 or 9, whereby the gear-wheels 19 will be rotated in opposite directions, and consequently the plungers caused to ascend or descend, and to efbe desired, or will throw the gear-wheels 19 out of engagement with either of the said pinions and prevent operation of the plungers. The levers may be held in the proper position by any desired means.

The press-box consists of two semi-cylindrical members 23, hinged together, having the interior lining 24, of reticulated material, the vertical bar 25, and the securing-bands 26, and the members are secured in any desired position, and the box rests upon a suitable board 27, having channels 28 in the lower side thereof.

The operation will be readily understood from the foregoing description, taken in connection with the drawings, and may be stated, briefly, as follows:

When it is desired to cause one of the plungers to descend,one of the gear-wheels 19 engages the pinion 8 which descends, and the other gear-wheels 19, being in engagement with the pinion 9,Wil1 receive motion in the reverse direction andascend, and each of the plungers can be operated to ascend and descend, or all of them, by merely shifting the gear-Wheels 19 from the pinions El and 9, and the plungers can be thrown out of operation by moving the gear-wheels 19 out of contact withv the pinions 8 and 9, as is evident.

The advantages of my improved press will be readily understood by all skilled in the art,

board 27 will be depressed and rest solidly on the bottom of channel 2. Whenthe plungers are withdrawn from the press-box, the board will be elevated by the springs 27, so that the rollers 27 will contact with the bottom of the gutter, and the board and pressboX can then be readily pulled out by means of the hook 27 I would have it understood that I do not limit myself to the minute details of construction and arrangement of parts, as such may be changed without departing from the spirit or sacrificing any of the advantages thereof.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- 1. In a press, the combination, with the base 1, uprights 3, cross-bars 4, the spindle 6, sleeve 7, fixed thereon, and the driving-shaft 10, having bevel-gear 12, of the bevel-gear 7 fixed to sleeve 7, the sleeve 8,loosely mounted on sleeve 7 and carrying the bevel-gear 8 and pinion 8 the pinion 9, secured to sleeve 7, the screw-threaded plunger 17, carrying vertically-reciproeating gear-wheel 19, and means, substantially as described, for reciprocating said wheel, as and for the purpose set forth.

2. In a press, the combination, with the base 1, uprights 3, cross-bars 4, spindle 6, having sleeve 7, and the driving-shaft 10, having bevel-gear 12, of the bevel-gear 7, fixed to sleeve 7, the sleeve 8, loosely mounted on sleeve 7 and carrying the bevel-gear 8' and pinion 8 the pinion 9', secured to sleeve 7, the screw-threaded plunger 17, carrying the vertically-reciprocating gear-wheel l9 and provided with groove 17, the hub 19' of said gear-wheel having annular recess 19 and key 19 the annular rings 22, engaging with said recess, the links 21, connected with said rings, and the lever 20, connected with said links, substantially as described.

In testimony that I claim the foregoing as my own I have hereunto afiixed my signature in presence of two witnesses.
